The paper presents an application of CFD simulations to predict a course of complex processes carried out in jet reactors. In this work the simulations results were verified with PIV and PLIF techniques and validated by comparing model predictions with experimental data for fast parallel chemical test reactions. Experimental results of BaSO4 precipitation in jet reactors are also discussed.
